Project CLEA -- CONTEMPORARY LABORATORY EXPERIENCES IN ASTRONOMY
-- develops laboratory exercises that illustrate modern astronomical techniques
using digital data and color images. They are suitable for high- school and college classes at all levels, but come with
defaults set for use in introductory astronomy classes for non-science majors.
Each CLEA laboratory exercise includes a dedicated computer program, a student
manual, and a technical guide for the instructor. The technical guides describe
file formats, user-settable options, and algorithms used in the programs. The
most advanced CLEA labs run under the latest versions of Windows on PC's (see note above regarding Windows 7 and 8 and Vista), or under Windows
emulation on Macintosh computers.

NOTE: This website is designed primarily to distribute software to
teachers and system adminstrators. It is not set up
for on-line use of the exercises. If you are an individual
using CLEA software in a class, you may find that downloading files and
documentation is a bit involved and requires some sophistication in the use of
computers. Consult your instructor if you are having difficulty downloading or
installing, since he or she should be familiar with the particular
circumstances of using CLEA software at your particular institution. However, for
all users, general instructions on downloading and installing can be found on
this website and in the CLEA technical manuals. Thanks for your interest in
Project CLEA and we look forward to hearing from you with comments and
suggestions!

After 22 years of support by NSF/NASA/and GETTYSBURG COLLEGE, we
are retiring from the development of further CLEA software. We
will continue to maintain this site, as long as possible, but are no
longer mailing out CD's. All software and manuals on this site may be
freely downloaded and used for educational, non-commercial purposes, as
long as you credit Project CLEA. Thanks to all our users and supporters!

CLEA IS NOW ON FACEBOOK! Become a
fan and contribute your ideas and questions on our discussion groups.
